Swift 几种动态判断类的方法

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        NVRLOG(touch.view)
        if (touch.view?.isKind(of:UITableView.self))! {
            return false
        }
        return true
    }

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        NVRLOG(touch.view)
        if NSStringFromClass((touch.view?.classForCoder)!) == "UITableViewCellContentView" {
            return false
        }
        return true
    }

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
        NVRLOG(touch.view)
      
        if touch.view is UITableView {
            return false
        }
        return true
    }
